Separating from my twin

So for 11th and 12th grade, I went to boarding school, but my twin sister still goes to our home high school.

This was really rough for me because I was what most people call the "submissive" twin and I always lead a life by "following the leader," aka my twin sister.

Going away to boarding school made me realize just how much I hadn't yet experienced as an independent person and I became a lot more comfortable with branching out and becoming my own person rather than a half of one.

I was thinking that... maybe.... for the princeton supplement that asks about "someone who influenced you in a significant way" that this could work? I know having a twin isn't all that special, but I think our separation did really impact me for the better.

However, I was also thinking that maybe I should focus more on the person who convinced me to stay at boarding school when I was really homesick without my sister and how she is the reason I stayed at school and became who I am today.....

Anyone have opinions?
